Project: Rational design of hierarchical zeolites for the synthesis of fine chemicals

Research group: Advanced materials

Project summary

Due to such useful characteristics as molecular sieving effect, high adsorption capacity, adjustable chemical composition zeolites are efficient catalysts of a number of large-scale processes. At the same time, despite showing unique and extremely useful properties, micropores impose restrictions on the mass transport of bulky reactants limiting the use of conventional zeolites in fine chemical or pharmaceutical synthetic applications. Last decade has brought a number of different strategies to accomplish the synthesis of zeolites with additional mesoporosity, i.e. hierarchical zeolites. The advantageous features of hierarchical zeolites (e.g. multilevel porosity, high concentration of acid sites with tunable strength) can be used to further extend the potential of zeolites to new applications in catalysis. The rational design of novel hierarchical (micro-mesoporous) zeolitic materials for catalytic applications is a general aim of proposed PhD thesis. The work will include both 1) the application of well-known synthetic techniques (e.g. removing of framework atoms) allowing fabrication hierarchical materials to novel objects (e.g. Ge-containing zeolites) and 2) further development of innovative approaches invented during last decade. This shall result in the preparation of a broad range of structurally and chemically diversified hierarchical zeolites followed by thorough investigation of structure – acidity – catalytic activity relationship in a set of acid-catalyzed reactions.
